Questions
How big is the DB10 PCB?
It measures 175.5 × 44 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DB10 use?
76 parts, built around the 74AHCT125D, APA102-2020 and 1N914WT. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the DB10 KiCad files?
From the lfg-seth/OpenControlHead repository on GitHub, at the commit this page was made from: the board is hardware/db10/DB10.kicad_pcb and its schematic hardware/db10/DB10.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DB10 design in my own project?
Its repository states no licence, so its author keeps all rights: ask lfg-seth before reusing the design.
